Hello Black Mesa Scientist, and friends of the Black Mesa Game, i have discovered something, and it led me to believe that it is directx related. I don’t really have a solution, probably if you look to update from microsoft or updater your directx files, unless you consider changing your OS to Win10 Pro as one solution. First time i played BMS steam, just after i bought it, i was on Windows 7 ultimate, directx 11; and last attempt on win7 was the last weeks of month december! And, every time i lauched the game via steam, as i supposed to, every single time the installer of dx poped up; and probably, failing; partially. Now, i got rid of that installing some dx pack from microsoft, one that did solve my problems among other games. But it seems, not on this one. But, eventually, i was going to upgrade anyway, since i love Win10 Pro. I opened it via steam, as usual, on the last week of december, using Windows 10 Professional with directx 11.1 this time, and dx12 for sound, also my current setup/OS. Guess what: only one time, One, the dx installer opened, the first time i ever launched the game under Win10 Pro OS. Aaaanndd,…SURPRISE. Once the game fully opened, i was looking at the menu, new game, overlay, etc. and…Listening to the Soundtrack! Now, what do you guys say? Since then i played 8 chapters, and every time, the soundtrack was, and is, there, even improved(sorry guys for the spoiler , etc. ). If you really HATE, like i did, “playing” with no soundtrack, and you are willing to change to Win10 Pro, the best out there my advise and evaluation, DO IT (or you can try to update your Windows OS directx instalation, but i don’t know to what result it leads). You can play with the mighty soundtrack, and have overall improvements too!(because os10, indeed).
Have a very safe, and productive day. :thumbup: [ProFist]
